I claim: 
     
       1. Sling-fitting equipment for an assault rifle of the AR15-M16 firearm family and equivalent models, comprising: a rear fixing member for fixing to a butt and a front fixing member for fixing to a barrel, a frontsight being carried by a quadrilateral support fixed to the barrel;   the butt being engaged on a tube screwed to the body of the firearm, and being fixed to the tube by a screw passing through the buttplate;   wherein: the rear fixing member comprises: a peg having a head pierced to receive a sling-engaging loop;   the head bearing against the butt on top and on the outside; and   the peg having a shank passing into the butt and being retained, free to rotate, in a retaining spacer carried by the rear end of the butt-support tube, between the tube and the buttplate;     the front fixing member being a peg fixed to the rear limb of the support for the frontsight, between the frontsight and the barrel, said member being constituted by a head having a hole for receiving the other sling swivel, and a threaded shank passing through the rear limb of the frontsight support, and receiving a nut secured by a pin.     
     
     
       2. Equipment according to claim 1, wherein the peg of the rear fixing member includes a groove in the portion of its shank which enters into the spacer and the spacer is provided with two holes for receiving two pins engaging in opposite sides of the groove to secure the peg to the spacer while allowing it to rotate about its own axis. 
     
     
       3. An assembly for putting into place the equipment according to claim 1, the assembly comprising: an L-shaped rear template having one limb that fits over the rear of the butt and another limb inclined at less than 90° relative to the first at the same slope as the buttplate and provided with a hole coinciding with the tube so as to enable it to be installed and fixed against the tube in the place of the buttplate;   the first limb having a hole lined with a bushing through which the butt can be drilled to enable it to receive the shank of the peg.   
     
     
       4. An assembly for putting into place the equipment according to claim 1, the assembly comprising an L-shaped front template, matching the shape of the frontsight support for its top portion that receives the frontsight and its other limb that slopes like the rear portion of the frontsight support, said template being provided in its first limb with a tommy-bar screw for engaging in the tapped hole for the frontsight once the frontsight has been removed, the rear limb including a drilling bushing through which a hole can be drilled in the rear limb to enable the sling swivel peg to be installed.
